Ikena Oncology Reports Third Quarter 2021 Financial Results and Corporate Update

IND for IK-930 accepted by FDA; Phase 1 clinical trial expected to initiate in early 2022

Progressing RAS pathway research programs with multiple development candidates expected in the next 18 months

Investigator-initiated trial launched evaluating IK-007 in combination with eribulin in recurrent/metastatic inflammatory breast cancer

BOSTON, Nov. 10, 2021 (GLOBE NEWSWIRE) -- Ikena Oncology, Inc. (Nasdaq: IKNA, “Ikena”, “Company”), a targeted oncology company focused on developing novel cancer therapies targeting key signaling pathways, today announced financial results for the quarter ended September 30, 2021. The Company also provided an update across the organization and pipeline, including the acceptance of an IND for their TEAD inhibitor, IK-930, as they advance it towards initiation of a Phase 1 clinical trial for patients with tumors known to have high incidence of Hippo pathway genetic alterations.

In addition to the Company’s progress on IK-930, Ikena is driving several programs targeting the RAS pathway. Emerging data from discovery and translational efforts have focused the team on key nodes in the RAS pathway that provide potential for clinical advancement of targeted therapies both as single agents and in combination to overcome therapeutic resistance in RAS mutated cancers. This work includes further efforts on ERK5 biology and chemistry optimization prior to candidate nomination, but also highlights new opportunities in the pathway. Multiple development candidates are expected to emerge from these RAS discovery programs over the next 18 months.

“Patients with mutations in the Hippo and RAS pathways represent cancer populations with significant unmet needs. At Ikena, we are committed to generating deep scientific support for our approach in these pathways and in the identification of therapies that could best treat their individual disease,” commented Mark Manfredi, Ph.D., Chief Executive Officer of Ikena. “The team has done tremendous work exploring TEAD biology, advancing IK-930, and generating robust translational data to optimize the clinical development plan. The IND acceptance is a foundational milestone for our targeted oncology portfolio and for our approach to biomarker-driven cancer treatments. The progress across the entirety of our pipeline demonstrates our commitment to science and medicine that will lead to better therapies with the best chance of helping patients.”

Summary of Recent Pipeline Progress and Corporate Update

IK-930: TEAD Inhibitor in the Hippo Signaling Pathway

IND accepted by the Food and Drug Administration (FDA); clinical trial expected to initiate in the first quarter of 2022

Program data was shared at the AACR-NCI-EORTC 2021 Virtual International Conference on Molecular Targets and Cancer Therapeutics

Data highlighted translational methods using a novel assay developed by Ikena and suggested YAP/TAZ activity could be a potential biomarker in determining patients that could benefit from TEAD inhibition

Preclinical data showed the importance of the Hippo pathway in resistance to EGFR and MEK inhibition and the potential of therapeutic combinations for patients, supporting our plans to evaluate combinations of IK-930 in multiple tumor types

RAS Pathway: Progressing Multiple Targets and Novel Approaches

Ikena has been expanding its discovery and translational research efforts in the RAS pathway beyond ERK5, with a particular focus on targeting nodes in the pathway that have potential for monotherapy and combinations both intra-pipeline and with other targeted agents

Continued drug discovery and additional translational efforts are being conducted prior to potential ERK5 candidate nomination. The RAS pathway discovery programs are expected to result in multiple targeted oncology development candidates in the next 18 months

IK-175 & IK-412: AHR Inhibitor and Kynurenine Degrading Enzyme Programs in Collaboration with Bristol Myers Squibb

IK-175 is currently being evaluated in a Phase 1 study to assess its impact in solid tumors and in urothelial carcinoma though aryl hydrocarbon receptor (AHR) inhibition

The study expanded its monotherapy cohort in urothelial carcinoma earlier this year and recently completed the dose escalation of the combination of IK-175 with nivolumab

The combination arm expansion cohort in urothelial carcinoma is now open for enrollment, including nuclear AHR positive enriched subset of patients

Three posters on IK-175 will be presented at the Society for Immunotherapy of Cancer Conference on November 12, 2021 highlighting translational data and a trial-in-progress presentation on the Phase 1 clinical trial design

IK-175 clinical data presentation is planned for a major medical conference in 2022

As previously reported, manufacturing lead times have been delayed for IK-412 and as such, Ikena and Bristol Myers Squibb are continuing to evaluate the best path forward

IK-007: EP4 Receptor Antagonist Currently in Phase 1 Clinical Trial

The IK-007 Phase 1 study in MSS colorectal cancer is on track to complete enrollment by the end of 2021; data will be submitted to a medical conference in 2022

An investigator-initiated trial (IIT) of IK-007 in combination with the chemotherapy agent eribulin in metastatic inflammatory breast cancer (IBC) led by Naoto Ueno, M.D., of the University of Texas MD Anderson Cancer Center was launched in September 2021

IBC is a rare, aggressive form of breast cancer with high unmet medical need

Increased COX-2 expression in the EP4 pathway has been associated with poor prognosis in IBC patients

Organizational Growth: Addition of Senior Clinical and Research Expertise

Ikena recently added deep expertise in clinical development, clinical operations, and cancer biology to the leadership team:

Karim Malek, M.D.: Vice President, Clinical Development

Medical oncologist with over 30 years of experience both in the clinic and in research and development, with strong academic roots

Joined Ikena from Takeda Pharmaceuticals where he was the global clinical lead on multiple immune-oncology platforms and garnered an extensive background in clinical trial design and execution

Jennifer Schroeder, PMP: SVP Clinical Development Operations Seasoned executive with nearly 25 years of experience ranging from start-ups to Fortune 500 companies

Served over a decade with Pfizer and was one of the founding business process owners where she helped implement clinical trial management systems and directed a globally focused team of seven leading enterprise-scale projects

Holly Koblish, Ph.D.: Vice President, Cancer Biology Over 20 years of experience in oncology drug discovery, asset development and target selection

Extensive drug discovery background as a pharmacology leader at Incyte, where she participated in the discovery of pemigatinib and capmatinib, two medicines recently approved in the U.S. and abroad

Financial Results for the Quarter Ended September 30, 2021

As of September 30, 2021, the Company had cash and cash equivalents totaling $245.9 million, which will fund operations through 2023. Net cash used in operations was $18.0 million for the third quarter of 2021 as compared to $7.7 million for the third quarter of 2020.

Research and development expenses for the third quarter 2021 were $13.4 million, compared to $7.2 million for the third quarter 2020. The increase in research and development expense was primarily attributable to IND-enabling studies, manufacturing development costs and clinical trial start-up costs for IK-930, manufacturing costs for IK-175, the on-going IND-enabling studies for IK-412, and research activities for other discovery stage programs. In addition, research and development expenses related to personnel and overhead expenses increased due to an increase in headcount. This increase in research and development expenses was partially offset by a decrease in development activities for IK-007.

General and administrative expenses for the third quarter were $4.9 million, compared to $1.8 million for the third quarter 2020. The increase was primarily attributable to an increase in compensation expense due to an increase in headcount and in insurance expense, as well as general increases in audit, legal, consulting and facilities expenses to support our operations as a public company.

Net loss for the third quarter 2021 was $14.5 million, compared to $6.2 million for the third quarter.
